How do playlists work? Can I use playlists from other apps, like iTunes?
For Android, playlists in the Play-Fi app use the standard Android playlist structure, shared by many popular music apps. Some music apps, like Google Play, use non-standard formats, so those playlists will not be visible in our app. You can also create new playlists from your stored music content right within the app.
For iOS, the app will display and use existing iTunes playlists. If you can't find your songs, be sure the music is stored on your mobile device and that they're not just stored in the cloud.
